rman數據遷移

環境：

備份數據庫

操作系統：oracle linux 6.3

IP地址：192.168.137.11

數據庫：Oracle 11.2.0.3.0

ORACLE_SID：normal

Global_name：normal

恢復數據庫

操作系統：oracle linux 6.3

IP地址：192.168.137.12

數據庫：Oracle 11.2.0.3.0

ORACLE_SID：normal

注意：上面恢復數據庫只安裝了數據庫軟件，沒有創建數據庫

--在備份前把rman中自動備份spfile和controlfile去了

--通過rman將備份的spfile_NORMAL_20140828_12_1恢復到數據庫
rman target /
startup 			--報錯沒關係
restore spfile to '/u01/app/oracle/product/11.2.0/db_1/dbs/spfilenormal.ora' from '/u01/app/oracle/backup/spfile_NORMAL_20140828_12_1';

--啓動數據庫到nomount
sqlplus / as sysdba
shutdown immediate
startup nomount

--通過rman恢復備份的control file
restore controlfile from '/u01/app/oracle/backup/ctl_NORMAL_20140828_11_1';

--將數據庫打開到 mount 狀態
alter database mount;

--指定備份文件所在目錄 並且 掃描整個目錄的備份片或者歸檔日誌文件等
catalog start with '/u01/app/oracle/backup';

--restore數據庫
restore database;

--recover 數據庫（注意這一步要在sqlplus中做，直接使用recover database會報錯。如下：） 
RMAN> recover database;
